Description

I

The invention relates to the field of mechanical engineering, mainly to devices for exhaust exhaust, in particular, internal combustion engines.

A device for removal of exhaust gases of an internal combustion engine is known, comprising an exhaust pipe section with a bell installed at the end of the pipe}.

A disadvantage of the known device is that b1 cotton gases are removed from the exhaust pipe only when the vehicle is moving, which reduces the efficiency of the device.

It is also known a device for removal of exhaust gases comprising an exhaust pipe section with a bell housed in a cylindrical housing open from the ends, and a cone placed in the latter, pointed apex toward the end of pipe 2.

This device allows the use of flowing air to eject exhaust gases from a pipe.

A disadvantage of the known device is that the vacuum created by the flow of the flowing device

air, insignificantly due to the unfavorable location of paths, along which air flows n gas.

The aim of the invention is to increase the efficiency of the device for exhaust gas emission from the internal combustion engine.

This goal is achieved by the fact that the bell is installed at the end of the pipe, and between it and the cone, the exchange for a conical shell, with the Ool & a4 base in the direction of the cone. In addition, the yrckn, which is pocketed between the shell and larger base of the shell, may be greater than the corresponding corners of the bell in the cone, the axial distance between the larger bases of each pair of adjacent parts of the bell, shell and the cone, may be less than the height corresponding to the male part. ; Digitometers of the big bases of the bell, cone and shell can be equal to each other; the distance between the apex of the cone and the plane passing through the larger base of the shell may be differences of the radii of the inner surface of the dilind. Fish cohosh and larger base of & yachi. The drawing shows the device, a longitudinal section. At the end of the exhaust section of the exhaust pipe 1 there is a bell 2 enclosed in a cylindrical housing 3 open from the ends. In the latter, there is also a housing 4 facing the end of the pipe 1. There is a conical shell 5 facing the end of pipe 2 and a large base facing the side of the cone 4. The trumpet 2, the shell 5 and the cone 4 of the mate with the casing 3 with the aid of lintel 6, Angle ". between the generator and the large base of the shell 5, there are more corresponding corners of the socket 2c. and cone 4cc. The axial distances between the large bases of each pair of adjacent parts: the socket 2 and the shell 5 and the shell 5 and the cone 4 are, respectively, less than P and a less than the heights of the corresponding parts covered. The diameters of the large bases of the socket 2, trunk 4, and shell 5 are equal to each other. The device works in the following way. The exhaust gases coming from the days of the internal combustion engine pass through the exhaust pipe 1 and enter the internal cavity of the casing 3. The flow into the spirit, penetrating as the vehicle moves through the open ends of the casing 3, creates rarefied air in the zone of the large bases of the socket 2, shell 5 and cone 4, which contributes to the effective removal of exhaust gases from the exhaust pipe. When the engine is running while the vehicle is stationary, the exhaust gases pass between the walls of the bell 2, shell 5 and cone 4 at a speed less than in the exhaust pipe, due to the appropriate choice of taper angles and distances between the socket 2, shell and cone 4. Created Exhaust gas discharge acts to remove gas from the exhaust pipe, and pushes the surrounding air into the cavity of the casing 3, which additionally reduces the temperature of the exhaust gases and their concentration. Such an embodiment of the device makes it possible to effectively remove the exhaust gases of the internal combustion engine from the exhaust pipe both when the vehicle is moving and when it stops. 1. An exhaust gas exhaust device, for example, an internal combustion engine, comprising an exhaust pipe section with a bell housed in a cylindrical housing open from the ends, and a cone in the latter facing the end of the pipe, characterized in that in order to increase the efficiency of work, the socket is installed at the end of the pipe and between them and the cone there is a conical shell, which is located with a large base towards the cone. 2. Device 4 p. 1, characterized in that the angle between the generator and the large axis of the shell more than corresponds to the corners of the bell and the cone. 3. The device according to paragraphs. 1 and 2, characterized in that the axial distance between the large bases of each pair of adjacent parts — the socket, the shell and the cone is smaller than the height of the corresponding male part. 4. Device PS nos. 1-3, which is distinguished by the fact that the diameters of the large bases of the restructuring, the cone and the shell are of a medium. 5. Device on PP. It is distinguished by the fact that the distance between the inlet and the plane passing through the larger base of the shell is equal to the difference between the internal surface of the cylindrical casing and the Large base of the shell.
